Hard to review but the changes look sound, so I only one question and a 
  comment.

I stumbled across this line "TODO check where $expTime is used, the new 
caching API can't handle it, so it can be removed". Does this mean that 
cached contents may never expire? How is the cache expiry to be handled?

Two new global variables are added: $cacheManager and $TYPO3_CACHE. What 
is the reasoning behind the different naming schemes? Even if 
$cacheManager may be used in theory in a wider context, it's a TYPO3 
variable. I know that the 5.0 team doesn't like singletons but I would 
appreciate if we could avoid new globals if possible. Actually I have no 
idea if there must be only one copy of the cache manager around, so 
maybe I'm on a wrong track here.
